Anime with 2 guys fighting over 1 girl?

A really short anime plox. :>

The only thing that I can think of right now is Tenjho Tenge. There are about 4 different girls that get fought over during the series.

Fruits Basket.

ACtually, all the guys in this anime fight over Tohru.

Bokura Ga Ita: Takeuchi and Yano fight over Takahashi. Good example imo
Vampire Knight: Zero, Yuki, and Kaname. Though Zero's feelings for Yuki are more noticeable in the second part of the seaon, it's still a good MxFxM triangle.
Paradise Kiss: If you want something even simpler, Arashi, Miwako and Hiroyuki are involved in a love triangle. Although the entire anime is mostly based on George and Yukari, there are many episodes/times that discuss those 3's love triangle. And even afterwards, Hiroyuki gets involved in another love triangle with George and Yukari (though it wasn't nearly covered as much as his previous love triangle-- only the surface was scratched.)

Kind of sort of in Xam'd: Lost Memories, between Furuichi and Akiyuki.

[xPiikanyaa]

Fruits Basket.

ACtually, all the guys in this anime fight over Tohru.

Dammit, I was gonna say that.

Maybe Cowboy Bebop..... But then that's not precisely....

[Kireblue]

possibly Shugo Chara. Tadase and Ikuto hate each other, but they both like Amu.

Tsubasa Reservoir Chronicles and Tsubasa Tokyo Revelations.

Basically, chronicles is about a clone named Syaoran (who doesn't know he's a clone) who falls in love with a princess named Sakura (oh the cliche!). By some act of god, she loses her memories (which turn into feathers) and he has to get them back. He trades his most precious possession (his relationship with the girl) to a witch who then gives him the power to travel to other universes and find her memories. The thing that sux is that all the memories erase him completely and the girl will never remember that she liked him too. Towards the end, the real Syaoran (who is actually called Shaoran) appears when the clone begins to lose his artificial heart/soul/humanity. This occurs in Tokyo Revelations. They follow each other and eventually have a standoff with Sakura suspended in a floating bubble. The two have an epic battle, but Sakura and her godly powers break free and she tries to stop the fight. She gets killed by both guys at the same time. Tears fall everywhere.
